ORE-FEEDER FOR SEPARATING-MACHINES.

Specification of Letters Patent.

rammed Apr. 25,191.1.

Application filed June 1, 1910. Serial No. 564,493.

citizen of the United States, residing at Berkeley. in the county of Alameda and Statev of California, have invented certainnew and useful Improvements in Ore-Feeders for Separating-Machines, of which the` fol-- lowing is a specification'. Y

The invention is mainly designed for the feeding of what is known as black sand to a centrifugal separator for the recovery ofthe gold values therefrom, which material is delivered to the feeder in substantially a dry condition; the object of the invention being to deliver the material to be treatedA should he had to the accompanying sheet of' drawings wherein- .Figure l is a vertical sectional view of a centrifugal separating 'apparatus with the invention applied thereto, and illustrated as situated within the downwardly inclined sluice-way communicating with the ore rcceiving' hopper for the separator. Fig. 2 is a horizontal sectional plan view `of the container for the material to be treated. Fig. 3 is a broken vertical sectional `view illustrating the container mon .ed within the sluier-way, said view mg than on line Fig. 2 of the drawings.

ln the drawings, the numeral l is used to designate an outer stationary bowl ot a centritugal separating apparatus, and-2 the'circulator mounted therein for rotation. Mw terial tor treatment delivered into the bowl l by means ot' the runway 5l, which leads` from a receiver 4.

Within an inclined sluice-way 5, dischargi ing,r into tho receiver vl, is located a container 63, (which is oi cylindrical torni and outwardly 'larod towardits lower end. container is an open bottomed one. and, in the present case, is held a slight distance above the surface ot' the sluice-way 5 by means ojt the downwardly extended supports T.

\Vit||in the bottoni ot' the container (3 is arranged a'plurality ot inverted V-shaped This i parallel ribs 8, which,when the container is positioned within Vthe sluice-Way 5, form longitudinally disposedpassages 9 Ifor the flow of waterJ through the containeremd the material containedtherein..v i.

Water may be supplied totheV sluice-way in `any suitable mannen, butffor the purpose of the presentinvention? the same is illustrated as coming from a supply tank 10, the water level in Whichpis above the sliceway, so that the same overflows into the said sluice-Way. i Then-supplyietank as ar'- v ranged receives the Itailin'gsfanddischarge water from `the circulator 2, A`whichdischarges therefrom into the trough 11, and are conveyed/thereby and deposited into the tank 10 to one side of the partition wall 12. Asv the `water frointhe Vhead supplyflows over the sluice-way 5, the sanne contacts with the exposed side walls ofthe material -held within the container 6, whichrrnaterial rests onthe surface of the sln-ieeway, and gradually undermines and` cuts awayothe saine, the water flow conveying the; released material into the receiver 4. Atthe same time, a portion ot' the water. flowing intothesluice- Way 5 will pass through the` channels or passa ges 9 andacting on the central portions of the heldimaterial cutsaway- -the same and carries such removedmaterial@.into the receiver 4t. tained material iscut away oru-ndermined, the entire body-of material, owing to the outward flare Aof the .container.6,y will'f'gradually give downwardly, :due tothe weight thereof, so that a new surface isexposed andpresented to the action of the flowing wat-er. The feed of material into the receiver 4- 'is thus automatically accomplished by the flowing body of Water passing through the sluice-way 5 andI beneath they container v(i, thusl giving a constant feed ofinaterial to betreated. The side cuts given to the Wall or embankment of held niaterial,` ikewise the centrally disposed cut, by the flow action of the stream passing through `the sluice-Way, cai. s a gradual removal or displacement of the mass oi confined material, the feed of such released material to the separator being conti-'oiled by the quantity rand head pressure ot water flowing through the sluice-Way.

rlo the upper end ot' the container (i is secured a receiving hopper 13, which receives As the bottom portion of the relso way should be'secured' within 4the .opent lo bottom of the ,container 6, for withoutt'he employmentthereof the feed of lthe held maf t l terialisa lslow oneand a tendency exists for Howeveigbyi, using lone-or moreribs 8, de-

eser/7s is claimed as new anudsieo to oef-secured by Letters Patent is- 1. In a feeder for separating machines, the combination with an inclined sluice-Way, of an open bottom container held therein a slight distance above the bottom of the sluice-way, one or more ribs located within the open` bottom of the-container and formingjvaterlways longitudinally disposed relative to and in close proximity to. the surface of thesluice-way, and means for admitting water into thesluiceway and longitudinally through the passage-ways formed by said ribs for acting against and 'removing the exposed portion-of the material within the container. f

2. In a-feeder for the described purpose, the 'saine comprising .an inclined tically disposed container held within the sluice-way a slight distance above the surface thereof, supports downwardly extended from shaped ribs arranged in the bottom of the eontainer'to form longitudinally disposed passages'or water-ways in close proximity to the surface ,of tlie s1uiceway, and means for supplying water to the said sluie-wuy and longitudinally -through the passages formedby said ribs for acting agamst, and

` 1 removing the exposed portion of. the material fr The described feeder is ,simple of `con projected beyond the open bottom v'of the container. y
